我试图将表格（由代码创建）的内容与标题对齐。到目前为止，我已尝试使用砝码，但它似乎无法正常工作

这是结果

                    LayoutParams.WRAP_CONTENT));
        }
    }
}

布局：

    <?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">



    <ScrollView 
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:id="@+id/scroll_view_system_description"
         >

        <FrameLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical"
             >

            <TableLayout
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:stretchColumns="*"
                android:id="@+id/tl_system_storical"
                >

            </TableLayout>
        </FrameLayout>

    </ScrollView>


</RelativeLayout>

我也试图修改权重值，但似乎没有任何区别。
